From idea to SaaS in six steps

A SaaS launches on a clear scope and a sound technical foundation. Features, screens and the launch version are decided with you before the first line of code.

Let's talk about your project

Book a 30-minute call

Step 01

The discovery call

You present your idea, your future users and the problem your SaaS needs to solve, during a thirty-minute call with no commitment. If an existing tool already does the job, we say so.

Step 02

The first version scoping session

We write the launch scope: sign-up, key features, subscriptions, roles and integrations, with the price. What is held over for the next version is noted separately.

Step 03

The clickable prototype

You click through the prototype as a future customer would, from sign-up to daily use. Your comments are built in and nothing is developed until you give the go-ahead.

Step 04

Developing the product

We build the SaaS in functional batches, on an architecture ready to grow. Each batch is delivered to you in staging for approval before we start the next.

Step 05

Launching the SaaS

We put the SaaS into production, test sign-ups, payments and emails with you, then hand over the access. You are trained to administer the platform.

Step 06

Product follow-up

Feedback from your first customers comes in. We handle maintenance and hosting, and develop the improvements you prioritise, version after version.

Honest advice

Is building a SaaS the right choice?

Not always. Here is how to decide honestly.

It is the right choice if

You have validated the need with real usersA first version can then be useful straight away.
Your idea doesn't fit into an existing toolCustom development becomes justified.
You want to remain the owner of your productThe code is yours.

It is not the right choice if

You haven't yet spoken to your future usersStart there, before developing.
A no-code tool is enough for testingTest first, develop later.

In those cases, we will tell you on the first call.

Book my call

It depends on the scope, which is exactly why we scope first: you leave the call with a clear scope and a fixed price, before any commitment.

No, and that is often what derails a project. We identify the core value, what your first users would pay for, and launch with that. The rest is built afterwards, guided by real usage rather than assumptions.

Yes: we can sign a confidentiality agreement before the first detailed discussion. The code, mock-ups and intellectual property produced for your SaaS belong to you, and we do not reuse your concept for anyone else.

Yes, billing is part of the product: plans, trial period, recurring payment, invoices, cancellation. We integrate a recognised payment provider rather than reinventing this building block, which limits the risks and the compliance burden.

The technical foundation is chosen so it can grow without rewriting everything. We don't oversize from the outset, which would be expensive for nothing, but we avoid choices that would block scaling up the day your product finds its audience.
